Frailty is a condition of increased vulnerability to exogenous and endogenous stressors, which is correlated with aging, functional decline, institutionalization, hospitalization, and mortality. Given the multifaceted nature of frailty, programs aimed at its prevention are recommended to act on multiple domains.
The present intervention program aimed at assessing the effects of combined physical and cognitive training in older people with mild cognitive impairment (MCI) and at investigating how their frailty status changed over one year of follow-up.
Two-hundred and seven participants were recruited among outpatients of the Cognitive Impairment Center who agreed to receive a comprehensive assessment. Forty-six participants, who joined a structured program of physical activity and group readings for a period of one year, were defined as active. The remaining 161, who decided not to engage in those activities, were considered controls. In both groups, frailty status was assessed at baseline and over one year of follow-up.
Control participants showed twice the risk of becoming frail at 12 months compared with those in the active group. Participants in the active group had more than three times the probability of improving their frailty status compared with the control group from T0 to T12. Age and NPI scores were significantly associated with worsening frailty status. When analyses were restricted to participants who were robust at baseline, the frailty status varied significantly between groups over time.
Findings of the present study confirm the beneficial effects of physical activity and reading to prevent frailty in older people with MCI.
衰弱是对外源和内源性应激源易感性增加的一种状态,与衰老、功能下降、机构化、住院和死亡相关。鉴于衰弱的多方面性质,建议针对其预防的方案作用于多个领域。
本干预方案旨在评估针对轻度认知障碍(MCI)老年人的联合身体和认知训练的效果,并研究其衰弱状态在一年随访期间如何变化。
在认知障碍中心的门诊患者中招募了 207 名参与者,他们同意接受全面评估。46 名参与者加入了为期一年的身体活动和小组阅读结构化计划,被定义为活跃组。其余 161 名决定不参与这些活动的参与者被视为对照组。在这两组中,在基线和一年的随访期间评估衰弱状态。
与活跃组相比,对照组参与者在 12 个月时衰弱的风险增加了两倍。与对照组相比,活跃组参与者在从 T0 到 T12 时改善衰弱状态的可能性高出三倍以上。年龄和 NPI 评分与衰弱状态恶化显著相关。当分析仅限于基线时身体健壮的参与者时,两组之间的衰弱状态随时间显著变化。
本研究的结果证实了身体活动和阅读对预防 MCI 老年人衰弱的有益作用。
